Ok - I appreciate everyone's responses: here's my results so far:

When I preload the videos anytime (especially the big ones) there's a 
mega lag.

When I drop the movie into the score, and just move it into location, it 
helps a bit, but still drops frames (both video & sound). Unless, of 
course, I preload the video that's sitting in the score (resulting in 
the mega lag ;)

I checked out our codec: it's Sorenson. But while I was doing that, I 
noticed that on the problem movie, the data rate was 1.5 MB/sec. Anyone 
have an idea if this is unrealistic for laptop cd-rom drives?

Interestingly, a similar movie @ 1.4MB/sec didn't hiccup noticably...I'm 
going to knock the compression up a bit to get more like 1000KB/sec and 
see if that solves the problem. Any body have an idea of the data rate 
ceiling?

Thanks for the help,

Evan
